QT252S-16.000MAHE-T

Overview

The QT252S-16.000MAHE-T is a surface-mount quartz crystal manufactured by QST. It operates at a fundamental frequency of 16 MHz with a load capacitance of 12 pF. The component features a seam seal package constructed from ceramic material, measuring 2.5 mm in length and 2.0 mm in width. Frequency stability is rated at ±30 ppm at 25°C and ±30 ppm across the industrial temperature range of -40°C to +85°C. The device utilizes a four-pad solder termination configuration for reliable surface mounting.

Feature Summary

Seam seal construction utilizing ceramic housing for environmental protection
Four-pad surface mount termination design for automated assembly
Industrial temperature range operation capability

Applications

Microcontroller clock sources
Communication module timing references
Digital signal processing circuits

Procurement Notes

Verify manufacturer authenticity through official channels. Confirm RoHS compliance status prior to integration. Ensure storage conditions maintain component integrity. Validate datasheet revisions against production requirements. Check availability constraints as distribution may vary by region.

Selection Notes

Select this component when a 16 MHz reference with moderate stability is required. Consider the 12 pF load capacitance requirement for circuit matching. Evaluate thermal performance needs against the specified temperature range. Compare physical dimensions against available PCB footprint space.

Part Context

This part belongs to the QT252S series of surface-mount crystals. The series offers various frequency options within the same mechanical form factor. Variants differ primarily in frequency, stability, and load capacitance specifications while maintaining consistent package dimensions.

Replacement Considerations

Direct substitutes include other manufacturers' 16 MHz crystals with identical 2.5x2.0 mm dimensions and 12 pF load capacitance. Verify pin compatibility and electrical parameters before substitution. Cross-reference stability ratings to ensure equivalent performance.
